The verdict: can you vibe code SeaTable?
Build a personal subset with Next.js and Liveblocks, or keep paying for the full platform — the real-time grid virtualization and sandboxed script execution engines represent a massive engineering undertaking.
Replicating SeaTable as a solo developer involves tackling several high-complexity engineering hurdles. While AI coding tools can bootstrap standard CRUD tables and basic UI layouts very quickly, implementing a bulletproof real-time collaborative grid with cell-level locking, virtualized rendering for 50,000+ rows, and a secure sandboxed execution environment for user Python scripts will easily consume months of grueling debugging. For a personal tool, you must aggressively descop: drop arbitrary Python script execution and advanced app-builder canvas features, relying instead on a standard Next.js stack with Liveblocks for multiplayer state.
Estimated effort: 3-5 months of part-time work

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js project structure, configure Tailwind CSS, set up Neon PostgreSQL connection, and implement better-auth for secure user authentication.
Create a new Next.js project configured with TypeScript, Tailwind CSS, and App Router. Set up Drizzle ORM to connect to a Neon PostgreSQL database. Define the database schema for bases, tables, columns (with dynamic data types such as text, number, single-select, multi-select, file, link), and rows. Implement better-auth with email/password authentication and secure session management. Ensure all migrations are clean and runnable via npm scripts.02Core Grid Base Editor & Virtualization
Build the high-performance relational spreadsheet grid view using TanStack Table and virtualization to smoothly render thousands of rows.
Build a spreadsheet grid component using TanStack Table and virtualized scrolling (via TanStack Virtual) to handle thousands of rows efficiently without DOM lag. Support inline cell editing with keyboard navigation (arrow keys, enter, tab), column sorting, filtering, and resizable columns. Implement dynamic cell renderers based on column types: text, dropdown selectors, checkboxes, and attachments.03Real-Time Collaboration via Liveblocks
Integrate Liveblocks to enable multi-user presence indicators, active cursors, and real-time cell change synchronization.
Integrate Liveblocks into the spreadsheet editor to provide real-time multiplayer collaboration. Implement room-based presence so users can see who is currently viewing or editing a base, display live colored cursors, and broadcast cell update events instantly. Handle conflict resolution gracefully when two users modify the same cell concurrently.04Alternative Layout Views (Kanban & Calendar)
Add alternative visualization layouts including a drag-and-drop Kanban board and a calendar view mapped directly to the table schema.
Build alternative view layouts for bases using dnd-kit for Kanban boards and a calendar grid view. The Kanban board should group rows by single-select column values and allow drag-and-drop status updates that instantly mutate the underlying database table. The calendar view should plot rows based on date columns with day/week/month toggles.05No-Code App Builder Canvas
Develop a lightweight drag-and-drop app builder interface allowing users to assemble custom internal dashboard pages from database tables.
Create a drag-and-drop No-Code App Builder interface. Users can create custom internal applications, add pages, and place UI components like metric cards, forms, and filtered table views connected to specific database tables. Implement a preview mode where end-users can interact with the published application layout.06AI Automations & Polish
Integrate Vercel AI SDK to enable natural language base queries, automated row generation, and final UI polishing.
Integrate the Vercel AI SDK to create an AI assistant panel within bases. Allow users to write natural language prompts that execute automated data queries, summarize table rows, or generate new records automatically. Perform a comprehensive code review, fix any type errors, and polish the user interface with clean loading states and toast notifications.

Vibe code SeaTable: FAQ
- Can you vibe code SeaTable yourself?
- Serious undertaking — 45/100 vibecodeable. Build a personal subset with Next.js and Liveblocks, or keep paying for the full platform — the real-time grid virtualization and sandboxed script execution engines represent a massive engineering undertaking.
- How long does it take to vibe code SeaTable?
- 3-5 months of part-time work — roughly 40-60 hours of hands-on time with an AI coding agent.
- How do you build your own SeaTable?
- Scoped to personal use: Next.js with Tailwind CSS, TanStack Table, and dnd-kit on the front, Next.js API routes / Node.js server with WebSockets behind it, PostgreSQL via Neon for data. Follow the 6-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own SeaTable without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 3-5 months of part-time work. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code SeaTable instead of paying?
- About ~$12 one-time to start and ~$5/mo to run, versus €7/mo (Plus Plan) for SeaTable. Break-even: Never (built for learning and custom control).
- What stack should you use to vibe code SeaTable?
